Why Are My Eyes So Dry? Lesser-Known Causes to Consider

Dry eyes are often linked to aging, contact lens use, prolonged screen time, and medical conditions like autoimmune diseases. While these are common culprits, many people experience dry eyes due to unexpected factors they may not realize are contributing to their discomfort.

At Eye Care Institute in Santa Rosa, California, our board-certified ophthalmologists and optometrists help people throughout Sonoma County determine the cause of their dry eye symptoms and find the right treatment.

Surprising Causes of Dry Eyes

If your eyes often feel dry and irritated but you’ve ruled out the usual suspects, one of these unexpected triggers may be the reason:

Sleeping with a Fan or Heater On: Air circulation from ceiling fans, heaters, and HVAC systems can dry out your eyes overnight.
Using the Wrong Eye Drops: Redness-relief drops may reduce redness temporarily but can make dryness worse over time. Preservative-free artificial tears are often a better option.
Dehydration and Diet: Not drinking enough water or lacking omega-3 fatty acids in your diet can contribute to poor tear production.
Makeup and Skincare Products: Waterproof mascaras, eyeliner applied along the waterline, and heavy face creams can block tear glands or migrate into the eyes, causing irritation.
Wearing the Wrong Sunglasses: Sunglasses without UV protection or wraparound coverage allow wind and sun exposure, which can lead to faster tear evaporation.
Air Conditioning and Indoor Air Quality: Dry indoor air from air conditioning, heating, and poor ventilation can strip moisture from the eyes, especially in offices and cars.
Alcohol and Caffeine Consumption: Both alcohol and caffeine dehydrate the body, which can reduce tear production.
Sleeping with Your Eyes Slightly Open: Some people unknowingly sleep with their eyes partially open, leading to overnight dryness.
Certain Medications: Some acne treatments, hormone therapies, decongestants, and blood pressure medications can contribute to dry eyes.

When to See an Eye Doctor

If your dryness does not improve with artificial tears, you frequently experience burning or gritty sensations, or your vision becomes blurry despite blinking, it may be time to seek professional care. Other warning signs include excessive tearing, redness, swelling, or light sensitivity, which could indicate more serious eye conditions.
